Generate the Variant value using sha1hex 1. We generate an equally distributed string of hex values, parse it to a length of 15, thats the max we can get before we blow out of the long range (fffffffffffffff)16 = (1152921504606846975)10 2. We turn that hex into its representative number 3. We find the remainder from 100 and use that as our variant bucket

Parameters:

contextKey - - the contexts unique identifier key

featureKey - - The feature key we are testing

salt - - A salt value

Returns:

hash - the hashed value

getVariantValue

public long getVariantValue(String hash)
